交叉编译libpcap-dev aarch64

Question

我正在尝试为arm64交叉编译libpcap-dev，我可以在armhf上正常工作，但是arm64给我带来了很多麻烦。

当前我正在安装所有编译器工具链

RUN apt update && apt install -y \
    gcc-arm* \
    gcc-aarch64* \
    libc6-dev-armhf-cross\
    libc6-dev-arm64-cross\
    byacc flex \
    libpcap-dev \
    file

然后我正在尝试使用此命令进行编译

export PCAPV=1.9.1
wget http://www.tcpdump.org/release/libpcap-$PCAPV.tar.gz
tar xvf libpcap-$PCAPV.tar.gz
cd libpcap-$PCAPV
export CC=aarch64-linux-gnueabi-gcc
./configure --host=aarch64-linux --with-pcap=linux
cat config.log
make

config.log文件看起来像这样：

configure:3034: result: no
configure: failed program was:
| /* confdefs.h */
| #define PACKAGE_NAME "pcap"
| #define PACKAGE_TARNAME "pcap"
| #define PACKAGE_VERSION "1.9.1"
| #define PACKAGE_STRING "pcap 1.9.1"
| #define PACKAGE_BUGREPORT ""
| #define PACKAGE_URL ""
| /* end confdefs.h.  */
| 
| int
| main ()
| {
| 
|   ;
|   return 0;
| }
configure:3039: error: in `/app/libpcap-1.9.1':
configure:3041: error: C compiler cannot create executables
See `config.log' for more details

我已经尝试过将设置变量设置为aarch64和arm64的每种组合，我想到了。我想我缺少明显的东西。

经过更多搜索后，我找到了答案。张贴在这里供后代使用。我设置了错误的编译器标志，它需要看起来像这样：

wget http://www.tcpdump.org/release/libpcap-$PCAPV.tar.gz
tar xvf libpcap-$PCAPV.tar.gz
cd libpcap-$PCAPV
export CC=aarch64-linux-gnu-gcc
export CFLAGS='-Os'
./configure --host=aarch64-unknown-linux-gnu --with-pcap=linux
cat config.log
make
